Hello.

 

"www.def.com" should be configured as a pool member resource.

 

You can use a rewrite profile or just modify the irule to replace these specific headers:

 

GET /URL=www.def.com/ghi HTTP/1.1

Host: www.abc.com

 

To get this:

 

GET /ghi HTTP/1.1

Host: www.def.com

 

If "www.def.com" page has references to relative path resources (let say href="/images/myimage.png") you should take this into account replacing the payload during the HTTP_RESPONSE.

 

Besides of URI and host header, there exist other headers that could need to put an eye of them.

  • Cookies
  • Content-Security-Policies
  • Etc

 

The best option is to connect the backend resource directly (with browser inspector) and try to investigate how your site is in order to plan your scope.

 

Regards,

Dario.
